TOOL FOR REMOVING SlCKLE-BARS.

Patented Jan. 30, 1906.

Application filed January 11, 1905. Serial No. 240,594..

To all whom it may concern:

Be it known that I, SAMUEL M. HILL, a citizen of the United States, residing at Sunnyside, in the county of Yakima and State of Washington, have invented certain new and useful Improvements inTools for Si ckle-B ars, of which the following is a specification.

This invention consists of a special tool for use on mowing-machines, reapers, and harvesters in removing the cutter or sickle bars where it is desired to grind or sharpen the sickle knives or sections or replace those broken or worn out. The usefulness of this tool is especially apparent when the sickle bar becomes gulnmed or clogged, so that it will not reciprocate freely in the finger-bar, and its removal for cleaning purposes is difficult when attempted in the usual way-4. 6., by striking against the lug, eye, or other projection on the head of the bar.

In the accompanying drawings, which form a part of this application, I have illustrated a preferred form of my invention in the following views:

Figure 1 shows the device complete. Fig. 2 is a fragmentary view, on a larger scale, showing one end of the device applied to a sickle-b ar, the head of the latter being shown. Fig. 3 is an end view of the device, and Fig. 4 shows a slightly-modified form of device.

Referring to the details of the drawings, A represents an iron bar adapted at one end. to have a chain, as B, attached thereto and at the opposite end formed with a claw-shaped head a. This head is hollowed out on its under side to form a socket a and is divided for a portion of its vertical diameter to provide a recess or notche which allows the head-to straddle the ordinary, sickle-bar C, thus permitting the head to secure a firm and effective contact with the pitman-head c on the bar C. The pitman-head is shown in a quasi-spherical form quite common in cutter-bars and is adapted to be grasped by the usual pitman-rod. (Not here shown.) One end of the chain has secured thereto a handle I), which is of a size and shape convenient for grasping by the hand.

In using the above-described device the pitman-head is freed from the pitman-rod in the usual manner and the claw-head a is attached. Then by pulling on the handle D the sickle-bar is drawn from the finger-bar. The operation is facilitated by permitting the chain to become slack, then pulling on the handle quickly, the resulting jerk on the pitman-head tending to loosen the sickle-bar by dislodging the obstruction Which has interfered with its operation. The gumming of sickle-bars is quite frequent when they are used for cutting certain grasses or plants on soil that is dry, so that dust mixes with the juices of the plants, so that frequent removal of the bar is necessary.

The flexible connection between the handle and the claw-head or bar permits the device to be carried easily in the tool-box, which forms apart of all machines of the class named.

In the modified form shown in Fig. 4 the claw-head a is formed without a handle, as A, but has the chain B secured directly thereto.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A tool for IGHIOVlDgPltlIlflJl-I'OClS, consistmg of a head recessed in its under side to ht over the pitman-head and formed with claws adapted to straddle the pitman-rod back of the head, a shank integral with. said head, and a chain connected with the end of said shank.

In testimony whereof I affix my signature in presence of two witnesses.
